A wireless router can typically connect up to how many devices?

• A. 100
• B. 250
• C. 500
• D. 1000

Answer: (B)

A wireless router’s ability to handle devices hinges on its hardware capacity to manage multiple client connections simultaneously. For typical consumer routers, the practical upper limit is around a few hundred devices, with about 250 being a common upper bound per radio. This limit comes from the router needing to maintain each device’s session, run network address translation, manage DHCP leases, and process wireless traffic. When more devices join, the router still connects them, but performance can degrade as CPU, memory, and bandwidth get shared among all clients. Enterprise-grade gear can handle far more, but home routers are designed for a balance of range, throughput, and stability. Among the options, 250 reflects the common maximum for a single consumer router.
